Caribbean economies suffer from some of the highest electricity prices in the world. Despite their abundance of renewable energy sources, Cayman has a relatively low level of renewable energy penetration; the economy continues to spend a large proportion of its GDP on imported fossil fuels.

The Caribbean Transitional Energy Conference (CTEC) is about building our resilience as a small nation, about diversifying our energy sector and the way that we do business.

It is about ensuring sustainable social and economic growth through strong leadership, recognising the threat of climate change and the vulnerability of islands across the world and voicing our commitment to take the measures that we can take now. More

By 2040, the world's power-generating capacity mix will have transformed: from today's system composed of two-thirds fossil fuels to one with 56% from zero-emission energy sources. Renewables will command just under 60% of the 9,786GW of new generating capacity installed over the next 25 years, and two-thirds of the $12.2 trillion of investment. • Economics – rather than policy – will increasingly drive the uptake of renewable technologies. All-in project costs for wind will come down by an average of 32% and solar 48% by 2040 due to steep experience curves and improved financing. Wind is already the cheapest form of new power generation capacity in Europe, Australia and Brazil and by 2026 it will be the least-cost option almost universally, with utility-scale PV likely to take that mantle by 2030.

• Over 54% of power capacity in OECD countries will be renewable energy capacity in 2040 – from a third in 2014. Developed countries are rapidly shifting from traditional centralised systems to more flexible and decentralised ones that are significantly less carbon-intensive. With about 882GW added over the next 25 years, small-scale PV will dominate both additions and installed capacity in the OECD, shifting the focus of the value chain to consumers and offering new opportunities for market share.

• In contrast, developing non-OECD countries will build 287GW a year to satisfy demand spurred by economic growth and rising electrification. This will require around $370bn of investment a year, or 80% of investment in power capacity worldwide. In total, developing countries will build nearly three times as much new capacity as developed nations, at 7,460GW – of which around half will be renewables. Coal and utility-scale PV will be neck and neck for additions as power-hungry countries use their low-cost domestic fossil-fuel reserves in the absence of strict pollution regulations.

• Solar will boom worldwide, accounting for 35% (3,429GW) of capacity additions and nearly a third ($3.7 trillion) of global investment, split evenly between small- and utility-scale installations: large-scale plants will increasingly out-compete wind, gas and coal in sunny locations, with a sustained boom post 2020 in developing countries, making it the number one sector in terms of capacity additions over the next 25 years.

• The real solar revolution will be on rooftops, driven by high residential and commercial power prices, and the availability of residential storage in some countries. Small-scale rooftop installations will reach socket parity in all major economies and provide a cheap substitute for diesel generation for those living outside the existing grid network in developing countries. By 2040, just under 13% of global generating capacity will be small-scale PV, though in some countries this share will be significantly higher.

• In industrialised economies, the link between economic growth and electricity consumption appears to be weakening. Power use fell with the financial crisis but has not bounced back strongly in the OECD as a whole, even as economic growth returned. This trend reflects an ongoing shift to services, consumers responding to high energy prices and improvements in energy efficiency. In OECD countries, power demand will be lower in 2040 than in 2014.

• The penetration of renewables will double to 46% of world electricity output by 2040 with variable renewable technologies such as wind and solar accounting for 30% of generation – up from 5% in 2014. As this penetration rises, countries will need to add flexible capacity that can help meet peak demand, as well as ramp up when solar comes off-line in the evening. More

Commenting on the design created by Florida based firm RS&H Group, CIAA’s CEO Albert Anderson said, “The interior design is very impressive and I am confident that once completed the new expanded airport will be a first-class terminal facility

The CI$55 million expansion project should take around three years to complete and will nearly triple the current space at the airport. Construction on the first phase of the project is expected to begin this summer.

Here is the Cayman Islands Government's chance to save money and show their support for alternative energy. Covering the roof and parking lots with solar panels, and using LED lighting would set an example for Caymanians and Caymanian businesses to follow. Editor

April 2015: The UN Environment Programme (UNEP) has launched a study on mini-grids that proposes ‘Mini-grid Pooling Facilities (MPFs)’ as a solution to overcoming key investment barriers. Presenting mini-grids as a critical solution for improving energy access globally, the study examines the challenges of associated investment risks and transaction costs, and proposes addressing these through project and capital pooling.

The report, titled ‘Increasing Private Capital Investment into Energy Access: The Case for Mini-grid Pooling Facilities’: provides an overview of mini-grids, including ownership models; identifies and examines two key investment barriers, namely risks to investment in emerging markets and project costs in developing economies; assesses the benefits and drawbacks of project pooling facilities; and explores MPF structures and stakeholders.

On risks, the study notes that mini-grids in emerging markets present a complex risk profile. In addition to discussing perceived risks, such as political or fuel cost volatility, the study examines risks to investment in mini-grids during the development, construction and operation phases, as well as across phases. The study also identifies high transaction costs in developing countries in the areas of project identification, evaluation and diligence, and platform development.

According to some estimates, achieving universal electricity access by 2030 will require mini-grids to serve over 65% of off-grid populations globally. Arguing for the need to develop new financing models to reach such levels of deployment, the report presents MPF as conceptual framework for private-sector financing that pools projects and capital to support the development of mini-grids internationally. According to the study, MPFs can diversify risk and increase capital requirements by strategic selection of projects into portfolios.

The report suggests that MPFs can also help: lower transaction costs through centralizing fixed expenses; decrease technology costs; attract previously unavailable capital; and leverage philanthropic investment, among others. The study stresses the need for developers, investors and researchers to work jointly, conducting proper analyses and determining the appropriate structures for each working context.

Al Gore has something of a reputation as the Cassandra of climate change. But amid the doom and gloom—melting glaciers, ever-rising carbon levels, accelerating species extinction—the former vice president has been positively sunny of late.

Why? Solar energy. “There is surprising—even shocking—good news: Our ability to convert sunshine into usable energy has become much cheaper far more rapidly than anyone had predicted,” Gore wrote recently in Rolling Stone. “By 2020—as the scale of deployments grows and the costs continue to decline—more than 80 percent of the world’s people will live in regions where solar will be competitive with electricity from other sources.”

Now a new report substantiates Gore’s optimism. Research firm Bloomberg New Energy Finance predicts renewable energy will account for 49 percent of the world’s power by 2030, with another 6 percent coming from carbon-free nuclear power plants. Solar, wind, and other emissions-free sources will account for 60 percent of the 5,579 gigawatts of new energy capacity expected to be installed between now and 2030, representing 65 percent of the $7.7 trillion that will be invested.

Gore is right that solar is driving the shift away from fossil fuels, thanks to plummeting prices for photovoltaic panels and the fact that solar fuel—sunshine—is free.

“A small-scale solar revolution will take place over the next 16 years thanks to increasingly attractive economics in both developed and developing countries, attracting the largest single share of cumulative investment over 2013–26,” the report states.

Solar will outpace wind as an energy source, with photovoltaic power accounting for an estimated 18 percent of worldwide energy capacity, compared to 12 percent for wind. That’s not surprising given that a solar panel can be put on just about any home or building where the sun shines. Erecting a 100-foot-tall wind turbine in your backyard usually isn’t an option.

In the United States, solar is projected to supply 10 percent of energy capacity, up from 1 percent today. In Germany, though, solar and wind will account for a whopping 52 percent of all power generated by 2030, according to the BNEF estimate.

These are all projections, of course, based on the existing pipeline of projects and national policies and involving a certain amount of guesswork.

The big wild card is what happens in developing nations like China and India, where energy demand is expected to skyrocket with a burgeoning middle class. Energy consumption will grow to an estimated 115 percent in China and 200 percent in India over the next 16 years. (Falling birth rates in the West mean that energy use will drop 2 percent in Japan, for instance, and 0.2 percent in Germany.)

Whether the world kicks its reliance on coal-fired electricity will depend in large part on what kind of energy choices China and India make. China installed a record amount of solar capacity last year and has set ambitious goals for ramping up renewable energy production.

The good news, though, is that individuals around the world can make a difference with their personal power choices. According to BNEF, much of the solar energy to be generated over the next 16 years will come from solar panels installed on residential roofs. More

The Energy Centre uses a field of more than 600 mirrors (known as heliostats) which are all directed at two towers housing solar receivers and turbines, Gizmag reports.

This supercritical steam is used to drive the world’s most advanced power plant turbines, but previously it’s only been possible to produce it by burning fossil fuels such as coal or gas.

“Instead of relying on burning fossil fuels to produce supercritical steam, this breakthrough demonstrates that the power plants of the future could instead be using the free, zero emission energy of the sun to achieve the same result,” Dr Wonhas explained.

Currently, commercial solar thermal or concentrating solar power power plants only operate a “subcritical” levels, using less pressurised steam. This means that they’ve never been able to match the output or efficiency of the world’s best fossil fuel power plants – until now.

The commercial development of this technology is still a fair way off, but this is an important first step towards a more sustainable future. More
